Sundar Pichai — Know what morning routine works best for you

The CEO of Google sets himself up for success every morning with his pre-dawn routine. Pichai digs into an omelette, drinks tea, and catches up on the news.

There's nothing flashy about this habit, but it works for him. "I'm not a morning person, so I need my time with my paper and tea to wake up and kind of get going," Pichai told Recode.

So take care of yourself in the morning. Do whatever you need to do to get yourself prepared for the rest of the day, whether that means going on a jog, curling up with a nice cup of coffee, or taking some time to contemplate your life.

By taking some time for yourself, you'll be setting yourself up to better tackle your goals throughout the day.

We all have to make countless decisions throughout the day. That's just life — but sometimes, all those choices can weigh us down.

The New York Times reported that decision fatigue is a real problem: "You can't make decision after decision without paying a biological price."

Angela Merkel — Consider all your options

Making fast, on-the-fly calls is the only way to accomplish your goals quickly, right?

Well, not really. In fact, rushing into decisions can seriously trip you up and further delay your progress.

It's better to follow the example of the German Chancellor. "For me it's important I deliberate all options ... running through scenarios, and not simply theoretical experiments in my head," she told the BBC.

According to Inc., it's almost always better to avoid impulsive decisions and instead base your choice on observing what's going on around you, as that will give you "the power to weigh those observations against your instincts."

Why two pizzas? Well, the more people you cram into a meeting, the less effective it will be. According to Fast Company, small groups tend to be far more innovative.

By cutting out unnecessary, useless meetings, Bezos is able to devote more time toward working to further his goals every day.

Once you've set your sights on your dream, don't give up on it.

Just look at JK Rowling.

In April, Rowling retweeted writer Melanie Dione's tweet, which urged people to finish their creative projects, regardless of whether or not they where sure anyone would watch, read, or listen to them. "There were so many times in the early 90s when I needed somebody to say this to me," Rowling wrote.

The author struggled financially before the "Harry Potter" series took off, Business Insider previously reported. She also received a ton of rejection letters before her fantasy series was picked up. However, she kept working and has since gone on to become one of the wealthiest people in the world, according to Forbes.
